Abstract

PURPOSE:To obtain the subject compound useful as a water-soluble amide monomer at low cost by reaction between (meth)acrylic acid and an acrylamide derivative. CONSTITUTION:The compound of formula II (R<3> is H or methyl) (e.g. 2- carbamoylethyl methacrylate) can be obtained by reaction pref. at 100-140 deg.C between (meth)acrylic acid and a compound of formula I (R<1> and R<2> are each H or 1-4C alkyl) (e.g. acrylamide, N,N-dimethyl acrylamide). The compound of the formula II by itself can be used in wide applications such as a reactive diluent for photosensitive resins and photoresists, or, in the form of polymer, a flocculant, dispersant, soil modifier, soil stabilizer, paper strengthening agent, adhesive or coating. By this method, the objective compound of formula II can be obtained in an industrially advantageous way without forming by- products using industrially inexpensive raw materials.
